I-Precision Plano-Concave kanye ne-Double Concave Lens
Incazelo Yomkhiqizo
Ilensi ye-plano-concave inendawo eyodwa eyisicaba kanye nendawo eyodwa egobile yangaphakathi, okwenza imisebe yokukhanya ihlukane. Lawa ma-lens avame ukusetshenziselwa ukulungisa umbono wabantu ababona eduze (i-myopic), njengoba enza ukuba ukukhanya okungena ehlweni kuphambukise ngaphambi kokuba kufinyelele kuyi-lens, ngaleyo ndlela kuvumele ukugxila ku-retina ngendlela efanele.
Amalensi e-Plano-concave nawo asetshenziswa ezinhlelweni zokubona ezifana nezibonakude, ama-microscopes, nezinye izinsimbi ezihlukahlukene njengezinjongo zokwakha izithombe namalensi ahlanganisayo. Zibuye zisetshenziswe kuma-expander we-laser beam kanye nezinhlelo zokusebenza zokubunjwa kwe-beam.
Amalensi ama-concave aphindwe kabili afana namalensi e-plano-concave kodwa anezindawo zombili ezigobile ngaphakathi, okuholela emisebeni yokukhanya ephambukayo. Asetshenziselwa ukusabalalisa nokugxila ekukhanyeni ezinhlelweni ezifana nezinsimbi ezibonakalayo, amasistimu wokuthwebula izithombe, namasistimu okukhanyisa. Zibuye zisetshenziswe ngokujwayelekile kuma-expander we-beam kanye nezinhlelo zokusebenza zokubunjwa kwe-beam.
Ukunemba kwe-plano-concave kanye namalensi a-Double-concave ayizingxenye ezibalulekile ezisetshenziswa kumadivayisi ahlukahlukene okubona. Lawa ma-lens aziwa ngokunemba kwawo okuphezulu, ukunemba kanye nekhwalithi. Asetshenziswa ezinhlelweni ezifana ne-microscopy, ubuchwepheshe be-laser kanye nemishini yezokwelapha. Lawa ma-lens aklanyelwe ukusiza ukuthuthukisa ukucaca kwesithombe, ukucaca nokugxila.
Amalensi e-plano-concave ane-precision anendawo eyisicaba ngakolunye uhlangothi kanye ne-concave kolunye. Lo mklamo usiza ekuhlukaniseni ukukhanya futhi usetshenziselwa ukulungisa noma ukulinganisa amalensi amahle kumasistimu okukhanya. Avame ukusetshenziswa ngokuhlanganiswa namanye amalensi amahle ohlelweni lokuthwebula izithombe ukuze kuncishiswe ukuphambana okuphelele kwesistimu.
Amalensi e-Biconcave, ngakolunye uhlangothi, ane-concave ezinhlangothini zombili futhi aziwa nangokuthi ama-biconcave lens. Asetshenziswa ngokuyinhloko ezinhlelweni zokuthwebula izithombe ukuze akhulise ukukhanya futhi anciphise ukukhuliswa okuphelele kwesistimu. Zibuye zisetshenziswe njengezandisi ze-beam noma izinciphisi ezinhlelweni ze-optical lapho kudingeka khona ama-diameter ancishisiwe.
Lawa ma-lens akhiqizwa kusetshenziswa izinto ezahlukahlukene ezifana nengilazi, ipulasitiki ne-quartz. Amalensi engilazi ayizinhlobo ezivame ukusetshenziswa ngokunemba zeplano-concave kanye ne-bi-concave lens. Aziwa ngama-optics ekhwalithi ephezulu aqinisekisa ukucaca okuhle kwesithombe.
Njengamanje, kunabakhiqizi abaningi abahlukahlukene abakhiqiza i-Precision Plano-Concave yekhwalithi ephezulu kanye namalensi e-Double Concave. E-Suzhou Jiujon Optics, i-Precision Plano-Concave kanye namalensi e-Double Concave enziwe ngengilazi yekhwalithi ephezulu, enezici ezinhle kakhulu zokubona. Amalensi aphansi ngokunembile ukuze kuqinisekiswe ukuthi ahlangabezana nezindinganiso eziqinile zekhwalithi, futhi atholakala ngebanga losayizi ukuze ahlangabezane nezidingo zezinhlelo zokusebenza ezahlukene.
I-precision plano-concave namalensi e-bi-concave ayizingxenye ezibalulekile ezisetshenziswa ezinhlelweni ezihlukahlukene, okuhlanganisa i-microscopy, ubuchwepheshe be-laser, kanye nemishini yezokwelapha. Lawa ma-lens adlala indima ebalulekile ekuthuthukiseni ukucaca kwesithombe, ukucaca nokugxila futhi akhiqizwa kusetshenziswa izinto ezahlukene ezifana nengilazi ne-quartz. Zaziwa ngokunemba kwazo okuphezulu, ukunemba, kanye nekhwalithi, zilungele izinhlelo zokusebenza ezidinga ama-optics asebenza kahle kakhulu.
